Phillips and Shi (2021) have argued that there may be some leakage from the estimate of the permanent component to what is meant to be the transitory component when one uses the Hodrick-Prescott filter. They argue that this can be eliminated by boosting the filter. We show that there is no...

Modulation format identification (MFI) and optical performance monitoring (OPM) are essential for elastic optical networks. A method for joint modulation format identification and optical signal-to-noise ratio (OSNR) monitoring based on ternary neural networks was proposed. Further, a ternary...
